If you're looking at he hydroboost from the front of the truck there's a little hole on the side of the hb cast body by the blue cylinder. Mine started leaking 2 months ago. After a whole bottle of Lucas stop leak didn't help i bought the reseal kit. Now it's not steady, on and off at random throughout the whole time. Tore it apart and rebuilt it. Stopped leaking about 3 weeks, now it'll randomly leave a puddle...... Anyone have this happen before? Is there a seal in that blue cylinder i missed? Said it's a sperate unit to purchase.
